I would be very happy about a checkbox to disable AJAX-Forms in comments for all blogs with one click.

After every update this (terrible) thing will be on. It is on if I put it off in the version before. And it does not works with the plugin of blueyed - his captchas (the best captcha plugin I ever had). So I need to deactivate AJAX form in every blog. And in this installation are a lot of blogs, really. And you need to deactivate in every one.

So it would great to have only one checkbox in general settings to disable this in every blog. Or make it like this list:

off for every blog

off for every blog, blog could overwrite it

on for every blog

on for every blog, blog could overwrite it

And it would really nice to put it in the database or the config file, so if I update b2evo it will read out this config and _not_ overwrite it with the next update.

At the beginning of the text line after the list, it should be "And it would really". In the text there is written "And it would really", so I cannot edit it to be correct. May be this is a bug of this b2evo too?

After thinking about this, I changed the title of the post and get a better idea:
In the settings there is one corner/tab for settings of all kind of blogs like in the list above.

So I can create new blogs very easy with defaults I like. And I can decide, if I want to make extra settings of every blog. And it should be possible, to save this config in the DB, so after an update/upgrade the settings will be the same (and not resetted like the AJAX form thing).

Maybe it is possible to get a page with a overview about the settings in all blogs so there is an easy way to compare the settings between the blogs and easy way to change some settings.

Right guess, the main suggestion is to let it be as it is. When it is deactivated, it should be deactivated after the upgrade.

The second suggestion is to have one master page for new blog. And it should be possible to change/edit its settings before I create a new blog/other thing - like the master site in pagemaker or other application which have this concept of a master page.

The second idea I got after I had written down the first post. Its a little bit mixed now, sorry about this.

And one week later, the upgrade to 5.2.2 will force the ajax forms on every blog again

You're right, but it's possible that recent comments and ideas don't make it right in the next release, especially if it's done one week later. Please check the changelog of the next release to see if this issue is already fixed, if it is not, you can avoid it by using the quick upgrade procedure (http://b2evolution.net/man/quick-upgrade-procedure).
